Two lethal injections carried out without incident

Months after a failed attempt at a lethal injection execution in Oklahoma, two states have put prisoners to death using the procedure.

In Georgia, a convicted teen killer was put to death.

Unlike Oklahoma, Georgia uses a single drug --pentobarbital --for executions.

And in Missouri, a man convicted of shooting his girlfriend and killing two of her friends in 1996 was executed.

There were no apparent problems with either procedure.
